Hi everyone, I have a Panasonic TX-28PL1 television in the living room, and I think BBC 1 and BBC 2 need to be retuned. I've had some problems with sky recently, which has required the removal of 2 faulty boxes. Needless to say, when one box is unplugged and taken away, the TV goes all fuzzy. I think all the unplugging and putting in new boxes has made the reception of BBC 1 and 2 below par. There are faint fuzzy lines going across the screen, with this being most noticeable on BBC 1. It does it slightly on BBC 2 but not on ITV 1 or Channel 4. Channel 5 has never been that good anyway, although it's worse than usual at the moment. When we've bought televisions, they have always been delivered and installed by an engineer. There has never been a need to re-tune any TVs in the house, until now. So, Ive never done it before. I've got an instruction book for the television, but there were a few questions I wanted to ask before doing anything about it. Will re-tuning these 2 channels mess up the video recorder settings, or will they be unchanged? And also, when retuning BBC 1 for example, do I put it on that channel when doing it? Any help would be great, thanks.
